Automasi konversi MRTG tradisional ke RRD tool Written by Administrator Saturday, 28 August 2004 14:47 -

Ide graffiti ini muncul dari artikel D. N. Indra Haryawan di http://www.infofreebsd.org dan merupakan lanjutan graffiti saya sebelumnya. Pemanfaatan rrdtool juga terilhami oleh tulisan pada site yang sama. (Maaf,.. saya lupa penulisnya) Brief : Bayangkan seandainya kita memiliki banyak host yang akan dimonitor via mrtg. Dan suatu saat kita harus mengupgrade-nya ke mode rrd yang di daemonized ? Tentunya akan cukup merepotnya bila menanganinya satu persatu... Nah loo... gimana donk ? So... akan lebih baik kalo prosesnya di automatisasi... ya Gak ? Step: 1. Download file 14all.cgi di http://my14all.sourceforge.net/ 2. Letakkan file tersebut pada path yang sama dengan file *.cfg lainnya , misal di /etc/mrtg (terserah sih,.. tapi ini favorit saya) 3. Ganti nama file hasil download tersebut menjadi 14all.cgi (or whatever), dan edit setelah baris : # (14all.cgi -> 14all.cfg) diberikan : $cfgfile = '/etc/mrtg/template-mrtg.cfg'; baris tersebut akan di parsing dan direplace oleh script 4. BUat script back up dulu #-----------------start script--------------------#!/bin/sh echo -n "Enter Path to Back Up : " read THEPATH echo "" echo -n "Enter Name Of Archive : " read ARCNAME tar -cf $ARCNAME.tar $THEPATH gzip $ARCNAME.tar echo "Done backup $THEPATH into $ARCNAME ...." #-----------------end script--------------------5. Run script di atas untuk membackup 6. Buat script conversi ini (jangan lupa edit seperlunya) #-----------------start script--------------------#!/bin/sh # This is my script to automatically convert convention mrtg .cfg files into rrd - daemonized mode # I usually use /etc/mrtg as my mrtg-path config

7. Chmod file diatas,... misal nama filenya converter,.. chmod +x converter 8. Edit file /etc/mrtg/make-index-rrd, seperlunya 9. Run /etc/mrtg/make-index-rrd 10. Hapus semua rekaman mrtg di crond 11. Buat customized startup, (seperti pada tulisan terhadulu) # ---------- start of script ---------#!/bin/sh DIR="/etc/mrtg" STRING1="/usr/local/mrtg-2/bin/mrtg /etc/mrtg" case "$1" in stop) for c in $(ps ax | grep mrtg | cut -c0-5) do PID=$(echo $c)

12. Chmod agar executable, dan sesuiakan dengan distro anda 13. Run script terakhir ini, dan... voila.... Note: Terima kasih xenogears atas tulisan yang sangat menarik ini. Sering-sering nulis yah :)
